Robert Earl Keen

Rather appropriately, mystery pervades the career of Robert Earl Keen, the most successful artist that many Americans have never heard. He’s had his songs recorded by George Strait, Lyle Lovett, Shawn Colvin, the Dixie Chicks and the Highwaymen (Waylon Jennings, Willie Nelson, Johnny Cash & Kris Kristofferson); appeared in such prestigious publications as Playboy and Men’s Journal; performed on “Late Night With Conan O’Brien” and “The Today Show”; and played concert venues steadily for more than 20 years. By his own admission, he’s never had a song hit the Top 10 of a major chart, and yet he consistently plays sold-out shows for audiences that number sometimes as many as 25,000.
